Dear Customer,
Thank you for choosing a Hanna Instruments product.

This instruction guide will provide you with the necessary

information for the correct use of the pipette. Please read it

carefully before using the pipette. If you need additional technical

information, do not hesitate to e-mail us at [email protected].

Please examine this product carefully. Make sure that no

damage has occurred during shipment. If there is any

damage, notify your Dealer.
Each pipette is supplied complete with:

• Two tips

• Instruction Guide

• Rigid carrying case

Note: Keep all packing material until you did verify that the

pipette works correctly. Any defective item must be
returned in its original packing.

PRELIMINARY EXAMINATION

1. Use the pipette in a vertical position whenever possible.
2. Operate slowly and smoothly. Aspiration and dispensing should

been carried-out with the same speed.

3. The tip should be immersed in the sample liquid the minimum

necessary (2-4 mm). Greater depths may cause inaccurate

measures.

4. Change the tip whenever a different kind of sample is to be

aspired or when droplets remain on the inside wall of the tip

from the previous pipetting operation.

5. Work always with samples at room temperature.

1. Liquid should never enter the pipette shaft. To avoid this:

• never use pipette without a tip
• do not invert pipette upside down or lay it flat when there

is a liquid in the tip

• press and release the push button slowly and smoothly.

2. When pipetting concentrated acids or alkalis or corrosive

solutions, pay particular attention to avoid contact of the

liquid with the pipette shaft, or it could be seriously damaged.

Extensive contact with corrosive fumes may result in premature

ageing of internal components of the pipette.

3. After use, store the pipette in its case or in a clean safe

place.

PIPETTE MAINTENANCE

GENERAL DESCRIPTION

designed to measure and transfer fixed volumes of liquids

that needs to be precisely dosed.
The liquid is aspirated into deposable tips. The use of

disposable tips eliminate cross contamination of the liquid

samples.

tip ejector to protect the user from contaminated tips.
